Methods, systems, and computer readable media for bridging user authentication, authorization, and access between web-based and telecom domains are disclosed. In one example, a method includes issuing, to an application hosted in a web-based network, an access token associated with a user identifier subscribed to a telecommunications network, wherein the access token is issued in response to receiving telecommunications network credentials from a client device associated with the user identifier and receiving, at an over the top (OTT) proxy element in the telecommunications network from the application, the access token for requesting user data associated with the client device to be used to access the application. The method further includes retrieving the user data if the access token is valid a telecommunications network context condition is met and providing the user data to the application, wherein access to the application by the client device is based on the user data.
